So you can now choose the valving that works specifically for you. The 20 Series is the highest quality sealed monotube shock available with custom valving on the market.

The 20 Series Sealed Monotube Shock has all of the high quality features of other QA1 shocks and also includes:

2” O.D. One Piece Steel Body

Coil-Over Ready

Linear and Digressive Valving Available

Linear Vs. Digressive Pistons
The linear piston creates a force curve that features an increase in force directly related to an increase in speed — the quicker the shock moves, the stiffer it becomes. The digressive piston creates a force that does not increase proportionately to an increase in speed — the force curve does not increase directly related to shock speed.
